Verified
When an intestinal cell ingests substances inside very small vesicles that can only be seen with an electron microscope, this is
A) pinocytosis.
B) phagocytosis.
C) exocytosis.
D) active transport.
E) diffusion.
Pinocytosis
A form of endocytosis in which cells engulf and internalize fluid along with dissolved substances.
Vesicles
Small membrane-bound sacs in cells used for the transport, storage, and digestion of substances.
Electron Microscope
A type of microscope that uses a beam of electrons to create an image of the specimen with much higher resolution than a light microscope.
- Describe the mechanisms cells use to ingest substances and the difference between pinocytosis, phagocytosis, and receptor-mediated endocytosis.

Final Answer :
A
Explanation :
Pinocytosis is the process of taking up very small particles or fluids by creating small vesicles within the cell. This process is commonly used by intestinal cells to absorb nutrients from the digestive tract.
